VALVE FOR STEAM OB WATER OR OTHER LIQUIDS 0R FLUIDS.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed July 19, 1913. Serial No. 779,971.

To all whom it may concern:

Be it known that we, J AMES CLAYTON and RICHARD TAYLOR, subjects of theKing of Great Britain and Ireland, and residents of Blackpool, in thecounty of Lancaster, England, have invented certain new and usefulImprovements in Valves for Steam or Water or other Liquids or Fluids, ofwhich the following is a specification.

This invention relates to valves which connect two pipes or pipesections and regulate the flow of gas or liquid through them; and itconsists in the novel construction and combination of the partshereinafter fully described and claimed.

In the drawings, Figure 1 is a longitudinal section through a valveconstructed according to this invention. Fig. 2 is a similar view, butshows a modification.

In accordance with our invention we employ a valve casing a or body ofany suitable shape, size and cross section and which incontradistinction to valves as ordinarily used is capable of rotationand movement in an axial direction, to enable the valve to be opened orclosed, that is to say, the body of the valve moves instead of thespindle as in ordinary valves. This valve body is provided internallywith a valve 7) cast with or attachable to it, such valve having acurved or spherical closure portion which may be detachable, if desired,as in Fig. 2 for renewal purposes and in any case adapted to be broughtinto contact with a seating a on the pipe main d or merely against theend of the pipe. Surrounding the valve closure portion and passingthrough its supporting wall 6 is a number of holes or slots 7, leavingarms 9, or arms and a ring by which the valve is supported within orsecured to the casing a. The valve and support may be arranged looselywithin the casing, if desired. The holes or slots 7 may be of anysuitable size so as to ofl'er as little obstruction as possible to theflow of the liquid or fluid. The valve arms 9 may also be of anysuitable cross section for the same reason. To arrange for opening orclosing the pipe main (Z, the valve is capable of being rotated andmoved along with the'casthreaded and a corresponding thread is formed atthe interior of one end of the casing a so that on turning such casingaround the valve is traversed toward and from the seat 0 to close oropen the pipe main. The opposite end i of the valve casing is mountedslidably upon a screwed extension h fitted to the opposite end of thepipe main cl. In order to retain a tight joint at each end of the casinga packing j is employed backed up by a ring 70 which is forced towardthe packing by a spring on in each case. The valve Z) is placed looselywithin the casing a which is made in two halves screwed together with apacking ring 11. between the faces. This arrangement allows of the valve6 being readily removed when required. The flange of the extension.

72, forms a piston s which slides watertight in a cylinder t formed inthe casing a, being kept watertight by the packing.

In Fig. 2 the valve portion 6 is separate from its wall 6, being securedthereto by means of a bolt 0 or the like. The valve is loose within thedivided casing a. as previously mentioned. In Fig. 2 the extension In isprovided with packing ring 79 on its periphery and the extension [L1with one or more packing rings 9. The arrangement is substantiallysimilar to that shown in Fig. 1 in other respect.

What we claim is:

The combination, with two straight pipe sections having their waterpassages arranged in line with each other, one of the pipe sectionshaving a screwthreaded extension, a piston, and a valve seat arrangedconcentric with the water passages; and the other pipe section having asmooth extension; of a revoluble and longitudinally movable valve casingprovided with screwthreaded and smooth portions which engage with therespective extensions and having also a cylinder in which the saidpiston slides watertight, and a valve plate secured to the valve casingso as to move longitudr set our hands in the presence of two WitnallyWith 1t and having a centrally arnesses.
